Abstract: A multi-core optical fiber has dimensions to be backwards compatible with a conventional, single-core optical fiber of the single-mode or multimode type. In one embodiment, the center core has a diameter, such as 3 to 9 um, 50 um or 62.5 um.

Abstract: A method and system connects multiple cores within one fiber, e.g., a multi-core fiber (MCF), to multiple fibers with single-cores. The single-core fibers can then be terminated by traditional envelopes, such as a single core LC envelope. A connector holds the single-core fibers into a pattern that matches a pattern of all, or a sub group, of the individual cores of the MCF. The single-core fibers may all be terminated to individual connectors to form a fanout or breakout cable. Alternatively, the single-core fibers may extend to another connector wherein the single-core fibers are regrouped into a pattern to mate with the cores of another MCF, hence forming a jumper. One or more of the single core fibers may be terminated along the length of the jumper to form a jumper with one or more tap accesses.

Abstract: A connector with at least one multi-core fiber (MCF) and method of attaching the MCF within the connector, includes inserting a first end of a MCF into a ferrule of a connector. Then, rotating the end of the MCF within the ferrule until a first selected satellite core of the MCF is in a first alignment relative to a feature of the connector. The feature may be a mark, indentation or protrusion formed on a ferrule, ferrule holder or connector envelope. Finally, affixing the MCF within the ferrule of the connector. In the case of an array-type connector, first ends of other MCFs may be added to the ferrule and clocked relative to the same feature of the connector. Second ends of one or more MCFs may be clocked relative to a same feature of a second connector.
